(Salt Lake City-AP) -- In the race to get Interstate 15 construction done before the 2002 Winter Games, engineers used some new techniques. Now, the Utah Department of Transportation wants to know how well those new methods are holding up. The department has commissioned a study through the University of Utah to examine highway durability.
On some of the new bridges, cracks can already be seen in the decks. The cracks are caused by salty water seeping into the concrete. A U-DOT officials says the cracks are normal, and after decades, the decks deteriorate to the point where they need to be replaced no matter how they are built.
The University engineers will be looking at that and other factors in the major overhaul of Utah's main north-south highway.
